Chemical Weapons - Greek Fire Incendiary devices were standard weapons of war. Wooden defences always needed protection from burning. Wet animal hides were highly effective against burning arrows so military engineers dedicated themselves to finding ways of ensuring that fires burned as long and as strongly as necessary to catch.

All sorts of chemicals could be used for this purpose - petroleum, sulphur, quicklime and tar barrels for example. Liquid fire is represented on Assyrian bas-reliefs.

At the siege of Plataea in BC the Spartans attempted to burn the town by piling up against the walls wood saturated with pitch and sulphur and setting it on fire, and at the siege of Delium in BC a cauldron containing pitch, sulphur and burning charcoal was placed against the walls.

A century later Aeneas Tacticus mentions a mixture of sulphur, pitch, charcoal, incense and tow packed in wooden vessels, ignited and thrown onto the decks of enemy ships.

On the other hand Greek fire was very hard to control, and it would often accidentally set Byzantine ships ablaze. The formula for Greek fire was a closely guarded secret and it remains a mystery to this day. The term Greek Fire was not attributed to it until the time of the European Crusades.


Muslims against whom the weapon was used called the Byzantines Romans. The weapon was first used by the Byzantine navy, and the most common method of deployment was to squirt it through a large bronze tube onto enemy ships. Usually the mixture would be stored in heated, pressurised barrels and projected through the tube by some sort of pump, operators being protected behind large iron shields.

Byzantines used Greek Fire only rarely, apparently out of fear that the secret mixture might fall into enemy hands.A solid-state drive or SSD is a storage device that uses integrated circuit assemblies as memory or interconnected flash memories to store data persistently even without power.
